CAB 11E-TERMINAL.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 23, 1907. Serial No. 358,944.

To all whom it may concern: l

Be it known that I, FRANK B. Cook, a citizen ot' the United States of America, residing at Chicago, in the county of Cook and State ol" Illinois, have invented a new and useful Cable-Terminal, oi which the following is a specification, reference being had to the accompanying drawings, illustrating same. j

My invention relates to cable terminals employed in connections with cables of various kinds for distributing the cable conductors and connecting same with the line conductors.

The principal objects oi my invention are to provide a cable terminal constructed of .two similar halves adapted to be secured together to form an inclosed terminal; to provide improved means in cable terminal for distributing the conductors oi the cable leading to the terminal; to provide an improved cable terminal of the incloseddiead type constructed of porcelain; to

provide improved means for accommodating and insulating the cable and the aerial conductors leading to the cable terminal; and to provide compactness, sim,- plicity of construction, and durability in such a cable terminal. Other objects will be apparent from the following specification.

In the accompanying drawings illustrating the preferred form of my invention, Figure 1 is a side elevation of the cable terminal of the invention; and Fig. 2 is a cross-sectional view of the terminal, taken on linea; :t of Fig. 1 with portions shown in elevation.

Like characters refer to like parts in the several figures.

- The terminal head is constructed of two similar halves 1 1 bolted together by bolts 2 2 preferably as shown in Fig. 2, with suitable gaskets 3 3 placed between the halves 1 1 to make an air-tight and moisturetight joint. Each hall 1 is provided with half holes-4 5 and 6 at the bottom end, and 7 at the top end, adapted to form holes 4 4 and 5 5 to accommodate the aerial conductors leading to the terminal, hole 6 G to accommodate the cable leading to the terminal, and hole 7 7 through which the cable head may be filled with an insulating compound, when the tw halves 1 1 are placed together. The gaskets 3 3 are preferably made in two straight strips, whichlcxtend along the side of the terminal from the outer end of hole 6 6 to the outer end of hole 7 7, holes (i G and 7 7 being preferably the same size.

8 indicates the inclosure of the terminal headadapted to accommodate the cable conductors and which is preferably to be filled with the insulating compound. Acork 9 is provided for the hole 7A 7, to

close same after the terminal has been properly installed. Each half 1 is provided with, recessesl() 10, preferably square or hexagonal, adapted to fit heads 11 11 of hollow bolts 12 12 to keep the bolts vfrom turning.

On the exterior snrlaceof each portion 1 are provided y,

cover 18 is placed to inclose the terminal as a'whole,

Each projecting edge portion 17 is provided with a series 'of holes 19 19 therethrough adapted to accommodate the aerial conductors 16 1G which lead from the holes 4 4 and 5 5 in the base of the terminal, through holes 19 19 in the portions 17 17 to bolts 12 12. The cable is insertedinto the 'hole G G in the base of the terminal, the Wires 22 22 of the cable being distributed to and through the hollow bolts 12 12 and soldered at the outer ends of bolts 12 12 by solder 2O which completely seals the openings 21 21 of the hollow bolts 12 12 and thereby seals the inclosure 8.8 of the terminal air and moisture tight. i

It will readily be seen that each circuit through the cable terminal is from a cable conductor 22 through a hollow bolt l2 and an aerial conductor or bridle wire 16 which extends through a hole 19 in a portion 17 and through one of the holes 4 4 or 5 5 in the base of the terminal. The hubs 13 13 are for the purposeo increasing the insulation between the terminal bolts 12 12. Each halt 1 of the terminal is provided with a half circular base portion 23 whichis suitably bolted to a mounting bracket 24 by bolt 25, the bracket-.24v

being cut away as at 26 2G to accommodate the flatf85 projecting portions 27 27 of the two halves 1 1 of the terminal, which project below the mounting bracket 24 as shown in Fig. 1. The sheet metal cover 18 preferably rests on the back portion 2S and the iront corner portions 29 29 of the bracket 2l which support' the cover in proper position. The portions 27 27 projecting below the mounting bracket 2-1 thoroughly insul-.tte the conductors extending through holes 4 4, 5 5 and G G from the metal mounting bracket 24. The hole (i G being preferably long, lorms a guide for the cable to hold same in proper vertical position. The cable leading to the terminal is preferably somewhat smaller than the hole G 6, the insulating compound used in the terminal filling the space between the cable and the hole G 6 so as to make a tight jointa-nd hold the cable rigidly in place.

In installing the terminal, one of the halves 1 1 is unbolted from the mounting bracket 24 and moved away from the other half l sullicieutly to allow the cable to be placed between the halves 1 l and the conductors 22 22 thereof distributed through *the hollow bolts 12 12. After the conductors 22 22 are thus distributed, the two halves are bolted together as shown in Fig. 2, by bolts 2 2. 'lhe conductors 22 22' are then soldered to the bolts 12 12 at 20 20, the solder sealing up all of the openings 2l 21 in the bolts 12 12. The inclosure S 8 may now be tlled with au insulatroo
